Implement test set for java fuzzing with new fuzzing platform

[Markoutte]

Description

At the moment there's very few tests for check common java fuzzing examples. We need to write test to cover:

1. Class accessibility test
2. Recursive objects
3. Generating choosing strategies for objects and collections
4. Mutation strategies for objects and collections
5. Type parameters and generics

This should cover a set of problems like #2001, #1990.

Context

Since java fuzzing is based on fuzzing platform and old implementation is going to be removed soon (#1896), better tests should be implemented to cover base cases.
